Ground2k4 v5.1 help me!!!!

A regard to everybody The trheads of the forum are almost all read me before writing and I need some explanation: 1)In Ground2k4s version 5.1 the VTP1s have been disabled. How do I do to now use some images photoreal??? do I have to use another program??? How do I do to add us the autogen??? 2) the VTP2 doesn't give me the possibility to use the autogen on personalized texture but in some posts I have read that eliminating the folder "TEXTURE" from the scenery and inserting the files BMP and AGN in world/texture the autogen works. I have tried but FS goes to crash 3) "using CUSTOM 242 and 243 is possible to use the autogen" but in Ground2k4 the values 242 and 243 aim to a texture 255 nonexistent. In short I have such, a confusion that I don't understand there more nothing. Can someone clarify me the all kindly??? Thanks, graces and anchor thanks Antonio
